That isn't just a wall, that is a retaining wall holding up the slope behind your pool!

Are you just planning to replace the tile with a different tile? I would not do a real wood product in that location and a wood-look tile or composite would look strange, because you would never use real wood in that application.

I think your tile is nice and works with the rest (that I can see). A modern wood look tile can look modern and tropical (think high-end resort in Bali) but I don’t think that would work with the other elements you have.

Have you consulted with the pool restoration company as to how far your project will go? Just tile or all coping and pool interior refinishing? You want to have a cohesive look and you want to have the big picture in mind. I also agree that a wood look tile will be wrong for this application. You will want to look at tiles that are conducive to the curve you have.
